A turbine diaphragm assembly comprising a hub and a spaced retaining ring with an arcuate array of investment cast nozzle blocks having interfitting shroud segments disposed therebetween with the exit edges of the nozzle blades being substantially radially disposed and the flow passages having constantly uniform throats throughout the full radial extents thereof to maximize turbine efficiency. Manufacture is effected by arcuately grooving the front side of a plate, disposing the arcuate nozzle block array in the groove and bonding the same therein, and removing the web from the other side of the plate to open the flow passages. |
